Application ined February 17, 14913. serial no. 748,806.

To all whom t may concern.

Be it known that we, JEROME R. GEORGE and. VICTOR E. EDWARDS, both citizens of the United States, residing at VOrceSter, in the county of lVorcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Rod-Straightening Malner that the straightening rollers may be easily and quickly released from theirl supports for purposes of removal or replacement.

A further object is to provide a machine which will be simple in construction and i j which will, at the same time, be efficient.

In the accompanying drawing, Figure 1 1s a side elevation of a rod stralghtenlng machine constructed' 1n accordance with our invention, andlig. 2 is a plan view of the machine shown in Fig. -1.

Like reference characters refer to similar parts in both figures.

The body or frame of the machine includes a'lower portionaor .base 1 and anupper portion or cap `@the base 1 being mounted in any suitable mannerupon foundations 3. Two straightening rollers 4 and 5 are mounted at their opposite ends in bearings carried by the sides of the base 1. Each side of the base 1, shown in Fig. 1, is formed to provide" two parallel vertical opposedguidcwaysG in which a bearing may slide vertically. The portion of the side of the -base 1 between the two guideways 6 forms a horizontal support 8 for the bearing7 to rest upon. The lower corners of the bearing are removed to obviate the necessity of fitting them into the angles formed by the guideways (3 and the supporting face 8 and, further, so that accumulationslof matter at these points will not interfere with the proper seatingof` the bearing. i A ,bearing 9 for the end of the roller 5, shpwn'iin Fig. 1 is similarly mounted upon a supporting face 10 and between vertical guideways 11 formed in the base 1, and similar bearings are also machine.

provided at the other end of each-ofthe rol1e'rs-4`and 5. y

A bar 12l is adjustably supported under each side of thebase 1 by rods 13, being held in-desired position on the rods 13 by means of nuts 13. The two bars 12 supportthe weight of the upper rollers 14, 15 and 16. Between the end. of the roller '14, shown in Fig. 1, and the supporting-bar 12thereunder 1s a vertical rod 17 extending through the corresponding side of the base 1. The upper end of this rod carries a saddle 18 in which rests a journal 19 formed at the end of the roller 14 and in which this journal may rotate. The lower end of the rod 17 .slides freely in an opening in the bar 12.

- Patented Feb.' 1, 191e.

Therod 17, however, carries a collar 20 secured adjustably in position on the ,rod by a nut 21 and the bar 12 carries an opposed'.

collar 22 surrounding the rod 17, a Spiral spring 23 l,being interposed between the collars 20 and 22 so as to provide a yieldable support for the rod 17 and the roller 14. Each'end of each of the upper'rollers 14, 15 and 16 is supported in a similar manner.

If a rod to be straightened be heavy and rigid, the mere weight of the upper rollers 14, 15 and 16 would not be 'suflicient to straighten the rod. It is necessary, therefore, to prevent upward motion of the upper rollers beyond a certain llimit. The journal v19 of the roller 14 is held by the saddle 18 against an upper bearing24, slidably supported in vertical opposed guideways25 formed in the corresponding side of the upper portion or cap 2 of the frame of the T he bearing 24 carries a thrust member 26 in line with a rod 27 which is in threaded engagement with the upper portion 2 of the frame of the machine. It is clear that by turning the rod 27 its vertical position may be adjusted to vary the. uppermost position of the roller 14. The' rod' 27 is turned by means of a worm gear 28 operated by a rod29 carrying a worm 30 and supported in brackets 31 and 32. The rod 29 carries a second worm 33 engaging a second worm gear 34 acting to adjust verticallythe bearing.' for the other end of the .roller 14. By turning a hand wheel 35 attached to the rod'29, the upper bearings for both ends of the rollers are adjusted simultaneously. Similar bearings and'adju'sting means there- 'against the upper face v2 may then be lifted from 'ing both setsof rollers with all their bear-v for are provided for rollers 15 and 16.

When a rod is being passed vthrough the machine in order to straighten it, the entire pressure ofsuch rod upon the upper set of rollers 15 and` 16' is, direction and the positon'of the bars 12 and the compression of the springs 23 are adjusted so as to hold the upper rollers firmly against the bearings 24.

The base l and the upper portion 2 of the frame .of the machine are lsecured to! gether by rods 36 pivoted to the -base l and lying normally in grooves 37 in the upper Iportion 2 of the machine, eac-h rod 3G being supplied'with a collar or washer 38 held n of the upper portion 2 of thefframe of the 39 passing through a slot 40 in the .upper end of the rod. By driving out the wedges 39 su/iiiciently to loosen them, the rods 36 may be swung outwardly, as shown in Fig. 1, thus releasing the upperA portion 2 ofthe frame of the machine. This upper portion the base "l, leavings supported upon the basel, the bearings 24 sliding from their guideways 25 vas the upper'portion 2 of the frame is raised. In-

asmuch as the bearings 24 and saddles 18 and the bearings carrying the upper rollers, 7 and-9 carrying the lowerrollers, do' not extendthrough arcs of more than 1809, each bearing and roller may now be lifted from the machine. vOne end of each'roller is provided with grooves 41, or is otherwise suitably formed, to be engaged by means for driving th'e'rollers in any desired-manner.l

"It will be noticed that each Ways vprovided for the 4lvarious bearings forms va recess Vwhich along the dividing line of the frame in order to free the diderent each of the other upper of course, in an upward v pairs of guideways may .such common space .1s

machine by a wedge L Inecessary a yielding support for pair of -guidel i opens,into a-"space between. the lower and upper portions of the correspondingbearings so 'that they may be removed im? media'tely andeasily from their various positions in the frame. It is obvious that this feature would be present in a machine in which each pair"ofguideways waslextended to a common plane, but it is referable to, form such guideways only su c'iently long to accommodate 'properly' their respective bearings, and it vrwill usually be found desirable to provide a common spacebetween the ."two portions of each endofltheframe into formed by the which the various recesses open. Provision of only in reducing the Wei ht of the machine, but also in lreducing t e lengths of the guidewaysand thus th amount of labor in forming and fitting them.

thus described our invention, what 'We claim as new and desire to secure by Letters Patent is: l

1.111 a rod straighteningmachine, a base portion, a setof rollers carried by said base portion, a detachable-cap portion,fa vset of rollers disposed within said cap portion, eac'haof said last and adjustable means,

y Having mentioned rollers,

carried by said base said yielding supports. y

2. A rod straightening machine including a frame having a' base portion and a detachable cap portion, a set of' rod straightening rollers'carried within said cap portion, a. support for each of the rollers, springs for'said supports to rest upon, an

adjustable support forsaid sprin s, whereby they forcesof the-springs may e simultaneously adjusted ..said support beingcarried by said base portion and a set "of cooperating rod straightening rollers carried within said base portion.
